Philips MSR Gold 575W 7800K Metal Halide Bulb

The Philips MSR Gold 575W 7800K Metal Halide Bulb is a high-intensity discharge lamp designed for professional stage, studio and entertainment lighting.

Suits venues needing intense daylight-balanced light

This lamp suits lighting designers and rental houses that require high-output, daylight-quality illumination for concerts, theatres or broadcast. It is not for buyers seeking a long-life installation bulb, as the rated lifetime is 750 hours. It is also unsuitable for fixtures that cannot accept a 575W double-ended metal halide source or that lack appropriate UV filtering and ballast gear.

575W double-ended MSR Gold with 750-hour life

The single specification that decides fit is the 575W double-ended MSR Gold format combined with a 750-hour rated life. Buyers must confirm their fixture accepts this exact lamp type and can accommodate the required ballast and thermal management; otherwise the lamp will not operate safely or achieve its rated performance.

Questions about this item

What double-ended base does the Philips MSR Gold 575W 7800K bulb need for mounting?

The lamp uses a double-ended base with gold-plated caps that fit matching double-ended sockets; the gold plating protects both the lamp pins and the holder from heat during operation.

Which orientation step is critical when installing this 575 W metal-halide lamp?

The lamp must be seated so both gold-plated caps make full, even contact in the double-ended holder; partial seating causes hot spots that shorten the 750-hour rated life.

When should the Philips MSR Gold 575W 7800K bulb be replaced?

Plan replacement at or before 750 hours of use; after this point output drops below the rated 41000 lumens and the 7800 K colour temperature can shift.
